Multiple Alleles

  • genes can have more than two alleles - multiple alleles
  • ABO blood group associated with 3 alleles with gene I, leading to production of different antigens on the surface of membranes of Red Blood Cells (RBC's)
  • IᴬIᴬ / IIᴼ  = antigen A
  • IᴮIᴮ/ IᴮIᴼ = antigen B
  • IᴬIᴮ = antigen AB
  • IᴼIᴼ= no production of either antigen
  • only 2 alleles can
